The 510(k) FDA didn't review first
The public 510(k) record can carry a field marking that an accredited third party, not FDA staff, conducted the initial review. FDA still signs the clearance. The field is real, FDA Radar already ingests it, and the record everyone reads past does not point it out.

A cleared device’s public record reads the same regardless of who did the reviewing. FDA signs every 510(k) decision. It doesn’t always write the review that led to it.
A voluntary program with a statutory clock
Under Section 523 of the FD&C Act — 21 U.S.C. § 360m— FDA accredits private organizations to conduct the initial review of certain low- to moderate-risk 510(k)s and recommend substantial equivalence or not. Participation is voluntary, for the submitter and the review organization both. What isn’t voluntary is FDA’s own clock once a recommendation lands: by statute, the agency has 30 calendar days from receiving the review organization’s package to issue its own final decision. FDA can still ask questions, disagree with the recommendation, or re-review the file outright. The accredited organization reviews. FDA decides.
The record does keep it
Unlike the Traditional, Special, and Abbreviated distinction, this one survives into the public data. openFDA’s 510(k) endpoint carries a field, third_party_flag, set when an accredited organization conducted the initial review. FDA Radar’s own ingestion reads it off every clearance it pulls and stores it as third_partyon that item’s record today — ahead of any feature built to surface it, because the field arrives free with every row the API already returns.
The pathway a 510(k) took is usually invisible. Who reviewed it doesn’t have to be.
Why it’s worth reading before you read the clock
A short gap between received and decided dates gets read as a fast review. Some of that speed can be the accredited-review track itself — a different process with its own 30-day final-decision clock layered on top of the review organization’s own timeline, not evidence that a product code is an easy path through FDA directly. Two clearances with the same gap between dates can have gone through entirely different reviewers. The flag is the one field that says which.
Per what FDA Radar monitors and how often, this is regulatory intelligence about a field in the public record, never regulatory advice about what a specific competitor’s review track means for a specific filing.
